As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of DSCL or MSCL to avoid unintended generation of Start or Stop
conditions.

This parameter is not tested but ensured by characterization. For endurance estimates in a specific
application, please consult the Total Endurance™ model which can be obtained from our web site.
